1 is a longitudinal sectional view schematically showing a dryer according to a preferred embodiment of the present invention.

Referring to FIG. 1, a dryer according to the present invention includes a cabinet 10 having an exterior and having a space 11 in which drying objects such as clothes are accommodated and dried therein.

The cabinet 10 is directly provided with a drying space 11 accommodates a drying object therein, and one side of the cabinet 10 is provided with a door 12 to open and close the drying space 11. .

In addition, one side of the cabinet 10 is provided with a hot air supply device 20 for supplying hot air to the drying space 11 to dry the object to be dried. The hot air supply device 20 is composed of a heater 21 for heating the introduced air, the condenser means 22 for dehumidifying the air for heating through the heater 21 in advance the heater 21 It is preferably provided in front of the. In particular, in the case of the circulating dryer, the air passing through the drying space 11 is introduced into the heater 21 and heated again. Since the air passing through the drying space 11 is humid air, the air is dehumidified. More preferred. This is because in order to improve the drying effect, it is necessary not only to increase the temperature of the air but also to supply dry air.

On the other hand, one side of the cabinet 10 is provided with an air passage 13 for guiding the heated air passing through the hot air supply device 20 to the drying space (11). In addition, a predetermined position of the drying space 11 is connected to the air passage 13 so that heated air is introduced into the drying space 11 and the drying space 11 receives moisture from the object to be dried through the drying space 11. It is provided with an outlet 16 through which air is discharged from the drying space 11.

Preferably, the inlet 15 is provided in the upper portion of the drying space 11, the outlet 16 is provided in the lower portion of the drying space 11, the hot air supply device 20 is the cabinet 10 It can be installed at the bottom.

Then, the air heated by the hot air supply device 20 has a property to rise upward, the hot air generated in the hot air supply device 20 can be smoothly supplied to the drying space (11). That is, the air heated while passing through the hot air supply device 20 may flow along the air passage 13, and may be smoothly supplied to the drying space 11 through the inlet 15.

In addition, the air flowing into the drying space 11 and drying the drying object flows to the lower portion of the drying space 11 while retaining the moisture contained in the drying object, and thus the drying space through the outlet 16. It can be discharged smoothly from (11). In addition, the discharged air may be introduced into the hot air supply device 20 to be dehumidified by the condensation means 22, heated by the heater 21, and supplied to the drying space 11 again.

Preferably, the discharge port 16 is provided with a filter 52 for filtering foreign matter contained in the air passing through the drying space 11, the fan to smooth the flow of air behind the filter 52 50 and a driving unit for driving the fan 50, that is, a predetermined motor 51 may be provided. Then, the air in the drying space 11 can be more smoothly discharged through the discharge port 16 by the fan 50, and the discharged air is returned to the hot air supply device 20 by the fan 50. It can be introduced and heated. That is, the fan 50 not only smoothly discharges air in the drying space 11 but also smoothly flows the entire air.

In addition, a lower portion of the cabinet 10 may further include a collecting part 60 for collecting condensed water generated in the drying space 11 or water contained in a drying object, and a lower surface of the drying space 11 may be provided. A drain hole 14 communicating with the water part 60 may be provided. Preferably, the drain 14 may be provided at the lowest position among the lower surfaces of the drying space (11). In addition, the water collecting unit 60 may be provided as a predetermined water tank in which water is accommodated, and may be detachably provided so that a user may empty it selectively. Of course, the water collecting unit 60 is not provided, and water drained from the drain 14 may be provided to immediately drain to the outside.

On the other hand, as shown in Figure 1, the dryer according to this embodiment is a cabinet type, the drying space 11 is provided directly inside the cabinet 10, if the drum type dryer, inside the cabinet 10 It may be further provided with a separate drum (not shown) and a separate drive unit for rotating the drum (not shown) provided to form a space to be accommodated to dry the drying object.

In addition, the dryer according to the present embodiment is a circulating dryer, provided that the flow of air is circulated. If the dryer is an exhaust type dryer, outside air flows into the hot air supply device 20 and air is discharged from the drying space 11. The configuration may be provided to allow the discharge to the outside.

On the other hand, the dryer according to the embodiment is further provided with a vibration generating device 30 for generating a vibration in the drying space (11). The vibration generating device 30 generates a sound wave having a predetermined frequency into the drying space 11, thereby generating vibration in the drying space (11).

As such, when the vibration generating device 30 is provided as well as the hot air supply device 20 to dry the object to be dried, the drying effect may be improved while using less energy.

Because, when vibration is generated in the drying space 11 by the vibration generating device 30, as the generated vibration is transmitted to the drying object, the moisture contained in the drying object is easily separated from the drying object by the vibration Because it can be.

Therefore, as compared with drying only by the heater 21 as in the conventional dryer, the load of the heater 21 can be reduced, thereby saving the energy consumed in the heater 21. In particular, in order to improve the drying effect, without causing the temperature of the air heated by the heater 21 to be raised too high, the vibration generator 30 may generate vibrations in the drying space 11, thereby drying clothes or the like. Damage to the object can be prevented.

Preferably, the vibration generating device 30 may be provided to generate ultrasonic vibration in the drying space (11). In general, ultrasonic waves refer to sound waves that humans cannot hear by hearing because their frequency is higher than 20 kHz (KHz). Recently, ultrasonic waves have been widely used for washing. This is because, when the ultrasonic wave is generated in the water, numerous bubbles are generated by the vibration of sound waves, and at this time, the bubble acts as a vacuum cleaner to remove foreign substances attached to the surface of the object. In particular, since the ultrasonic waves vibrate water tens of thousands of times a second, it may be as effective as tapping with a laundry bat.

Therefore, similarly to using ultrasonic waves for cleaning, when ultrasonic vibration is generated in the drying space 11, the moisture contained in the drying space 11 may be vibrated tens of thousands of times per second, and thus included in the drying object. As the moisture can be separated more easily, the drying effect can be further improved.

On the other hand, the dryer according to the present invention may be further provided in the drying space 11, the mounting portion 40 for mounting the drying object. The mounting portion 40 may be provided in the form of a hanger or the like, but is preferably rotatably provided by a separate device.

Because, the vibration generating device 40 is provided on one side of the cabinet 10 to generate vibration in the drying space 11, in this case vibration only occurs in one portion of the drying object mounted on the mounting portion 40 This is because vibration cannot be generated in all parts of the object to be dried. Of course, a plurality of vibration generating devices 40 may be provided to generate vibrations in all parts of the object to be dried, but this is not preferable due to manufacturing cost or space limitation. Therefore, if the mounting portion 40 is rotatably provided in the drying space 11, even if the vibration generating device 30 is provided to generate vibration to any one side of the drying space 11, Vibration may be generated in all parts, and thus all parts of the object to be dried may be dried more effectively.

To this end, as shown in Figure 1, the mounting portion 40 is a predetermined portion of the motor 41 to enable the rotatable, the support portion 43 to be supported while the drying object such as clothing, and the motor 41 ) And the connection part 42 connecting the support part 43. However, the specific configuration of the mounting portion 40 is only one embodiment, of course, other constructions that allow the object to be dried, such as clothing is mounted on the support 43 is of course possible.

On the other hand, when a drying object such as clothing is placed on the holder 40, moisture contained in the drying object by gravity is collected at the lower part of the drying object, and thus, the lower part of the drying object is not easily dried.

Therefore, if the vibration generating device 30 is provided to generate vibration in the lower portion of the drying object mounted on the mounting portion 40, the lower portion of the drying object can be dried more effectively. To this end, the vibration generating device 30 may be installed at a height spaced a predetermined distance from the lower surface of the drying space (11). In general, when the object to be dried, such as clothing is mounted on the mounting portion 40, because it comes down to a height spaced apart from the lower surface of the drying space (11).

At this time, the mounting portion 40 is preferably provided to enable height adjustment in the vertical direction by the user. Since the mounting portion 40 is configured to enable the height adjustment in the vertical direction will be apparent to those skilled in the art, a detailed description thereof will be omitted.

In general, since the length of the drying object such as clothing is different, when the drying object is mounted on the mounting portion 40, the lower portion of the drying object does not come down to the height at which the vibration generating device 30 is installed. Therefore, the user can conveniently adjust the height of the mounting portion 40 so that the lower end of the drying object is lowered to the height of the vibration generating device 30, when mounting the drying object to the mounting portion 40, the convenience Do.

In addition, the vibration generating device 40 may be provided to be movable in the vertical direction on one side of the cabinet, in addition to the height adjustment of the mounting portion 40.

Figure 2 is a longitudinal sectional view schematically showing a dryer according to another embodiment of the present invention.

Since the present embodiment differs only in the hot air supply device 20 as compared with the above embodiment, the description or reference numerals for other components use the reference numerals and the description in the above embodiment.

Referring to FIG. 2, the hot air supply device 70 according to the present embodiment includes an evaporator 71, a compressor 72, and a condenser 73 in which a refrigerant circulates, and includes a heat pump for heating the introduced air. . That is, the dryer according to FIG. 1 is provided with a heater 21 as a hot air supply device, but the dryer according to the present embodiment has a difference in that a heat pump 70 is provided as a hot air supply device.

Hereinafter, the heat pump 70 which is a hot air supply device according to the present embodiment will be described in detail.

The heat pump 70 condenses and dries moisture in the inflowing air, and transfers the latent heat generated by the condensation to the condenser 73 which will be described later, and the latent heat transferred from the evaporator 71. And a condenser 73 for heating the air. That is, the heat pump 70 according to the present embodiment heats the air introduced into the condenser 73, thereby supplying high temperature air into the drying space 11.

At this time, the air introduced into the evaporator 71 may be dried by condensing moisture in the evaporator 71. That is, the refrigerant evaporates inside the evaporator 132, whereby the moisture in the air passing through the outside of the evaporator 132 is cooled and condensed to condensed water, and the air is removed to become dry air. Therefore, as in the dryer shown in Figure 1, there is an advantage that it does not need to be provided with a separate condensation means for dehumidifying the introduced air.

Preferably, a condensate storage unit (not shown) for collecting the condensed water condensed in the evaporator 71 is further provided, or the condensed water collecting unit 60 in which the condensed water condensed in the evaporator 71 is collected in the drying space 11. It may be provided to be collected.

On the other hand, condensation of moisture in the air in the evaporator 71 to dry the air and at the same time the latent heat is stored in the evaporator (71). That is, as moisture in the air is condensed, the refrigerant inside the evaporator 71 is vaporized to include latent heat. The latent heat contained in the refrigerant is transferred to the condenser 73 to be described later and used to heat the air.

That is, the condenser 73 according to the present embodiment is connected to the evaporator and the compressor 72 by a refrigerant pipe (not shown). Therefore, the refrigerant including latent heat in the evaporator 71 is supplied to the condenser 73 through the compressor 72 through a refrigerant pipe (not shown), and the refrigerant is condensed in the condenser 73 to discharge latent heat to condense 73. Heats the air flowing through it.

Therefore, the evaporator 71 condenses moisture contained in the air to dry the air, and at the same time, transfers latent heat generated by condensation of moisture to the condenser 73 through the refrigerant, and the condenser 73 condenses the refrigerant. Air is heated by releasing latent heat.

On the other hand, when the air is dried and heated by the heat pump 70 according to the present embodiment and supplied to the drying space 11, the air is heated by the condenser 73, so that the temperature of the air uses a heater. It can be lower compared to the dryer according to FIG. 1. Therefore, in the present embodiment, a heater (not shown) for heating the air passing through the condenser 73 may be further provided at the distal end of the condenser 73.

As such, when the heater is further provided, the air dried and heated by the condenser 73 of the heat pump 70 can be heated again by the heater and supplied to the drying space 11 at a desired temperature. Therefore, the air is preheated by the condenser 73 and heated by the heater, so that the load on the heater can be significantly reduced. That is, it becomes possible to heat air to a desired temperature using less energy compared with the dryer according to FIG. 1, and furthermore, it becomes possible to heat even with a small heater.

3 is a graph showing the relationship between the drying effect of the vibration generating device and the amount of water contained in the drying object.

The y-axis of the graph shown in FIG. 3 represents the amount of water contained in the object to be dried, and the x-axis represents the time when the vibration generator 30 is operated.

Referring to FIG. 3, when the amount of moisture contained in the dry object is large, the amount of moisture contained in the dry object is remarkably reduced by the operation of the vibration generator 30, but when the amount of moisture contained in the dry object is small, the vibration generator Even if (30) is operated, it can be seen that the amount of moisture contained in the object to be dried is hardly reduced.

That is, the drying effect of the vibration generating device 30 is more effective as the amount of moisture contained in the drying object is more effective, and if the amount of moisture contained in the drying object is less than or equal to a predetermined amount, it is understood that the drying effect by the vibration generating device 30 is hardly achieved. Can be.

This is because the vibration generating device 30 generates vibrations in the moisture contained in the object to be dried, so that the moisture is easily separated from the object to be dried, so that the drying effect is improved. This is because the effect is reduced.

Therefore, it is necessary to control the operation of the vibration generating device 30 in the drying process according to the amount of moisture contained in the drying object.

For example, the vibration generating device 30 may be driven from the start of the drying process until the amount of moisture in the drying object is reduced to A, that is, for the period t1 (section C). In addition, the vibration generating device 30 may be driven when the amount of moisture in the drying object is B to stop the vibration generating device 30 when the amount of moisture in the drying object is A. FIG. That is, the vibration generating device 30 can be driven only during t1 (t section D) at t2. Then, the energy consumption for driving the vibration generating device 30 can be minimized and the drying effect can be maximized.

4 is a configuration diagram schematically showing a configuration of a dryer according to the present invention.

Referring to FIG. 4, the dryer according to the present invention includes a humidity sensor 110 for detecting the humidity of the air discharged from the drying space 11 and a vibration generating device according to the humidity detected by the humidity sensor 110. The controller 100 may further include a controller 100 for controlling the driving of the apparatus 30.

As described above, in order to increase the drying effect due to the driving of the vibration generating device 30, the amount of moisture contained in the drying object should be large. In this embodiment, in order to detect the amount of moisture contained in the drying object, drying The humidity sensor 110 for detecting the humidity of the air discharged from the space 11 is provided.

That is, in this embodiment, by sensing the humidity of the air discharged from the drying space 11 to indirectly detect the amount of moisture contained in the drying object. Since the air discharged from the drying space 11 is air discharged with the moisture contained in the drying object contained in the drying space 11, when the humidity of the air is sensed, the amount of moisture contained in the drying object is indirectly measured. Able to know.

The humidity sensor 110 is preferably provided at the outlet 16 through which the air passing through the drying space 11 is discharged, or in front of the fan 50 to smoothly discharge the air in the drying space 11. Do. The outlet 16 or the fan 50 is a place where air in the drying space 11 is directly discharged. When the humidity sensor 110 is provided at the outlet 16 or the fan 50, the drying space 11 is provided. This is because the humidity of the air discharged from the air can be detected more accurately.

The control unit 100 preferably controls the vibration generator 30 to be driven only when the humidity sensed by the humidity sensor 110 is greater than or equal to a predetermined range or within a predetermined range. If the humidity sensed by the humidity sensor 110 is high, since the amount of moisture contained in the drying object is large, then driving the vibration generating device 30 at this time can achieve the maximum drying effect.

For example, at the start of drying, since the amount of moisture contained in the drying object is large, the humidity detected by the humidity sensor 110 will be high, and if the drying proceeds for a predetermined time, the amount of moisture contained in the drying object is gradually increased. As it decreases, the humidity sensed by the humidity sensor 110 will be smaller.

In this case, the controller 100 drives the vibration generator 30 at the start of drying, and when the humidity is detected by the humidity sensor 110 when the drying is performed, the vibration generator 30 of the vibration generator 30 It stops driving.

On the other hand, when the amount of moisture contained in the object to be dried is not enough to drive the vibration generating device 30 from the beginning, the control unit 100 does not operate the driving of the vibration generating device 30. Will not.

Therefore, the control unit 100 is driven by the vibration generating device 30 only when the drying effect can be increased by driving the vibration generating device 30 according to the humidity sensed by the humidity sensor 110, The drying effect can be maximized while saving energy.

5 is a view showing a control method of a dryer according to the present invention.

Referring to Figure 5, the control method of the dryer according to the invention the step of detecting the humidity of the air discharged from the drying space (S10), and controlling the driving of the vibration generating device 30 in accordance with the humidity Step S20 may be included.

Controlling the driving of the vibration generating device (S20) includes driving the vibration generating device 30 at the same time as the operation of the hot air supply device 20, and driving the vibration generating device when the humidity is less than a predetermined value. It can be made to stop.

At the start of drying, since the amount of moisture contained in the object to be dried is generally large, the vibration generating device 30 is driven simultaneously with the operation of the hot air supply device 20, and then the humidity detected by the humidity sensor 110 is applied. This is because it is preferable to stop the driving of the vibration generating device 20.

On the other hand, controlling the operation of the vibration generating device (S20) is a step of driving the vibration generating device 30 after a predetermined time after the operation of the hot air supply device 20, and the vibration when the humidity is less than the predetermined The driving of the generator may be stopped.

In general, since a sufficient drying effect can be obtained only by driving the hot air supply device 20 at the beginning of drying, after the drying effect obtained only by the hot air supply device 20 is obtained, that is, after a predetermined time. Driving the vibration generator 30 may minimize energy consumption. That is, by minimizing the driving time of the vibration generating device 30 is to minimize the energy consumption required to drive the vibration generating device (30).

Preferably, the step (S20) of controlling the driving of the vibration generating device may control the vibration generating device 30 to be driven together with the operation of the hot air supply device 20 only when the humidity is within a predetermined range. .

That is, the vibration generator 30 is not driven at the same time as the operation of the hot air supplier 20 or after a predetermined time elapses, but the driving of the vibration generator 30 is performed during the operation of the hot air supplier 20. It is to be made according to the humidity. As described above, it is because the amount of water contained in the object to be dried is not suitable to drive the vibration generating device 30 from the beginning.
